Apple Unveils 2025 Foundation Language Models Report

Apple has developed two advanced multilingual, multimodal foundation language models: a 3-billion-parameter on-device model optimized for Apple silicon and a scalable server model using a novel PT-MoE transformer, both supporting multiple languages and image understanding. These models power Apple Intelligence features across devices and services, with a focus on responsible AI, privacy, and developer integration through a new Swift-based framework. They outperform comparable open models in benchmarks and human evaluations, enhancing user experiences with efficient, accurate, and responsible AI capabilities.
